LOL.

Educate yourself:

My finite element analysis is a bit rusty and I do not know the relative
elastic properties of the stays that run from the head tube to the rear hub
(what would they be called on this bike?), the chainstays and the "seat
tube", but I still think this is a reasonable approximation unless I am
missing some secret ingredient.

So if I am wrong in my assumptions about how this thing works, then I ask
you: How does it work?
